Given the following question:


y^2=x^2-9x+2

Y^2 = x^2 - 9x +2


\begin{gathered} \sqrt[]{y^2}=^{}\pm x^2-9x+2 \\ \text{Plus or minus already lets you know that they're more than one value for y for ever value of x} \end{gathered}

Your answer is no, the equation does not define y as a function of x.
